UV History

In the late 19th century, scientists discovered that bacteria laden water could be disinfected when exposed to direct sunlight. Since that time, scientists have researched the properties of sunlight, specifically the UV-C part of the spectrum. The UV-C rays from the sun act as a natural sterilization system, inhibiting the growth and reproduction of biological pollutants. Hospitals, food processing facilities and water treatment plants have all used UV light as an effective disinfectant for over 30 years. The technology is proven and recognized by the Environmental Protection Agency (EPA), Food and Drug Administration (FDA) and United States Department of Agriculture (USDA) as a valid and effective means of eliminating biological contaminants.

How UV-C Works

UV-C rays kill viruses, bacteria, mold and other pollutants by penetrating their cell membranes, destroying their DNA and dismantling their reproductive capabilities. Unlike typical household cleaners, UV-C is chemical free and does not produce emissions, residues or odors. This means less harsh chemicals polluting our water and less unnecessary product packaging in our landfills.

Ozone History

Ozone, a form of activated oxygen generally produced during lighting storms and continuously occurring in the stratosphere due to the action of ultraviolet (UV) rays, was originally discovered in the 19th Century. Since that time, the sanitation properties of ozone have been put to various uses. For over 100 years, Europe has used ozone to treat drinking water and as a sanitization agent. In 1982 the FDA declared ozone a GRAS (Generally Recognized As Safe) treatment for bottled water. In 1997 the FDA was presented with a study that affirms the history and safety of ozone use with foods. Today, a number of large cities use ozone to sanitize local water and produce.

How Ozone Works

Ozone (O3) is a molecule made up of 3 atoms of oxygen. Ozone is very unstable – the extra oxygen atom looks to attach to any particle or pollutant available. When the single oxygen (O1) molecule attaches and oxidizes the particle, it is destroyed. Because of its high oxidation potential, ozone oxidizes cell components of the bacterial cell wall. Once ozone has entered the cell, it oxidizes all essential components (enzymes, proteins, DNA, RNA). The cellular membrane is damaged during this process, causing the cell to fall apart. In bacteria, ozone disrupts the integrity of the cell envelope through oxidation of the phospholipids and lipoproteins. In fungi, ozone inhibits cell growth at certain stages. With viruses, the ozone damages the viral capsid and upsets the reproductive cycle by disrupting the virus to cell contact with peroxidation. The only by-product of this process is clean, breathable oxygen (O2).

How UV-C and Ozone work together

UV-C works vertically - it only sanitizes what it can “touch”. On the other hand, Ozone, as a gas, is able to move around and through the object to reach the areas UV rays cannot. As an example, imagine disinfecting a toothbrush. The UV-C will hit the top of the bristles on the brush and the handle. Ozone will move into and around the bristles to disinfect what the UV rays do not. By using both methods, you ensure that the item is properly sanitized.
